Goodbye Everyone... A Final Showdown to Beat Everyone

Daichi (Hiroki Narimiya) gets into a fight with Nagasaki (Yuta Furukawa) and his gang to protect Hana (Riisa Naka) from them. Under the direction of his homeroom teacher Sakai (Minagawa Sarutoki), he is placed under house arrest. Hana asks Chiba (Yu Koyanagi), Rinpu (Haruna Kawaguchi), and their classmates to sign a petition to prevent Daichi from being expelled from school, but their response is cold and no one agrees to sign the petition.
